The student's average speed for the dash was 8.2 m/s. It's not possible to completely describe the student's velocity, because there's no information to tell us what direction she ran.
Given the the current flowing in the circuit and the elapsed time, the charge that passes through the LED is 1260 Coulombs.
<h3>What is Current?</h3>
Current is simply the rate of flow of charged particles i.e electrons caused by EMF or voltage.
If a charge passes through the cross-section of a conductor in a given time, the current I is expressed as;
I = Q/t
Where Q is the charge and t is time elapsed.
Given the data in the question;
- Time elapsed t = 1hr = 3600s
- Current I = 350mA = 0.35A
We substitute our given values into the expression above to determine the charge.
I = Q/t
Q = I × t
Q = 0.35A × 3600s
Q = 1260C
Therefore, given the the current flowing in the circuit and the elapsed time, the charge that passes through the LED is 1260 Coulombs.

#SPJ1
Weight equals mass multiplied by the acceleration due to gravity.
Answer:
Explanation:
Frequency of each electromagnetic wave is same thus we can interfere them along X axis in Phase diagram.
In phase diagram indicate each wave as vector with amplitude as length and phase difference as angle. (shown in attachment)
Now take component of E2 and E3 amplitude along X direction.
Net amplitude of all E in X direction = 
+ cos(45)[ 
+ ]
⇒ 
Final resultant have no change in frequency
So , resultant is
This can be explain through Newton’s first law of motion where an
object at rest remain in rest unless acted upon by an unbalanced force. Hence,
the dust particles having inertia and trapped within the pores of the carpet
has the tendency to remain at the state of rest, it does not move and resist
motion but when the carpet is beaten with a stick, dust comes out because the
force from a stick acted upon it.
